Two new malic acid derivatives, namely eucomic acid 1-methyl ester (2) and 6'''-acetylmilitaline (7), together with ten known compounds (1, 3-6, 8-12), were isolated from the dry tubers of Bletilla striata (Thunb.) Reichb. F., a perennial traditional Chinese medicinal herb, which was used for the treatment of pneumonophthisis, pneumonorrhagia, tuberculosis, and hemorrhage of the stomach or lung. Their structures were elucidated by spectroscopic analyses, including 1D-, 2D-NMR, and HR-ESI-MS.
从多年生传统中药材白及（Bletilla striata (Thunb.) Reichb. F.）的干燥块茎中分离得到两种新的苹果酸衍生物，即杜仲酸1 - 甲酯（2）和6'''- 乙酰基米立他林（7），以及十种已知化合物（1, 3 - 6, 8 - 12）。白及用于治疗肺结核、肺出血、结核病以及胃或肺出血。通过光谱分析，包括一维、二维核磁共振以及高分辨电喷雾电离质谱对它们的结构进行了阐明。
